The gas diffusion electrode (GDE) in a zinc-air battery (ZAB) plays a critical role in determining battery performance by allowing oxygen to transfer from the air and undergo electrochemical reactions. However, traditional GDE approaches overlook the sluggish oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) as well as catalyst poisoning and corrosion, which reduce battery capacity and lifespan. To overcome these challenges, here we propose the synthesis of bimetallic and trime
